The tape measure shows only three centimeters of difference between the two, but anyone who's carried both knows the day-to-day impact runs much deeper than that. The Kelly 25 measures approximately 25 cm x 19 cm x 9 cm, and the Kelly 28 reaches 28 cm x 22 cm x 10 cm, enough to completely change what fits inside.
Each size's personality shifts along with the space. The 25 tends to look more delicate and refined, almost an accessory for special occasions, while the 28 is often described as the true sweet spot of the Kelly family, roomy enough to carry the essentials without looking bulky, a favorite among those already experienced with the brand.
Anyone choosing their first Kelly from the collection might want to think about how they plan to use it. Those who already know they'll carry it all day (work, appointments, commuting) tend to be more satisfied with the 28. Those after a piece for a specific occasion, a dinner or a more formal look, find exactly the right proportion in the 25.
